its about kazuki and tokiko that fight homunculus using kurogane... its a hilarious and exciting anime.... (^.-)



Story

The story begins when high school student Kazuki Muto (武藤カズキ, Mutō Kazuki?) is killed one night saving a mysterious girl from a monster, only to wake up in his school dorm, believing it to be a dream. However, he soon finds out that dream wasn't a dream at all when a giant serpentine monster attacks him and his sister. Tokiko Tsumura (津村斗貴子, Tsumura Tokiko?), the girl he saved, explains that the monster is a homunculus. Kazuki had been attacked and killed by it when rescuing Tokiko, however she, feeling responsible for him, revived him by placing a Kakugane medal in his chest, serving as a replacement heart.

The Kakugane, as Tokiko explains, is an alchemical device that, when activated, takes a certain form based on the Kakugane user, forming a unique Buso Renkin. The Buso Renkin is the only thing that can destroy a homunculus monster. Using this, Kazuki creates his own Buso Renkin, taking the form of a giant lance, later named 'Sunlight Heart'. Along with Tokiko and her own Buso Renkin (the Valkyrie Skirt, an execution scythe), Kazuki joins the fight against the homunculi and their master.

Alchemy
In the world of Buso Renkin, there are two types of alchemy besides the historical one: buso renkin (arms alchemy) and homunculus.

Busou Renkin
Buso Renkin are weapons formed by the alchemically-created kakugane, based on the user's will to fight. The shape the Buso Renkin takes reflects the user's personality. Buso Renkin are the only weapons known to be able to kill a homunculus. Kakugane are developed in the process of creating the Philosopher's stone, the ultimate goal of the Alchemy Warriors around the planet. Kakugane will generate a weapon that reflects the user's battle style; a user will always have the same type of Buso Renkin regardless of the Kakugane number, though there will be cosmetic differences (note, this occurs when something about the person using the Kakugane changes or if they use multiple Kakugane in battle.) Buso Renkin are activated by the fighting instinct of their user. This means that they can only be used by humans or human-type homunculi, since only humans have the instinct to use tools to defend themselves (animal- and plant-type homunculi's instincts have them fight with their bodies). Kakugane, in their normal state, can also strengthen a user's healing abilities. In total, there are only 100 Kakugane, from I (1) to C (100) (note, the first three of which were turned into Black Kakugane and the second one was made into a White Kakugane after that). After the Victor Incident, Kakugane were scattered around the world; currently, there are 25 known Kakugane that are used in Japan.

Black Kakugane
Black Kakugane I-III are the first results of the Alchemy Warriors. However, they were unstable, and upon insertion of Black Kakugane I (1) to replace his heart, Warrior Victor went berserk. The same thing would happen to Kazuki 100 years later when his Black Kakugane III (disguised as Kakugane LXX) awoke. A person who has been revived using a black Kakugane is called a 'Victor,' since he was the first person to become such a being. Black Kakugane give their users glowing light green hair, red eyes, and tanned skin, (but in the anime, green glowing hair) with the ability to use 'Energy Drain,' a 'vital body function' which absorbs people's life force; it's possible to kill a person by draining his/her energy. As it is a vital body function (like breathing), it is impossible to stop or shut it off. Black Kakugane users also have the ability to evolve. While in stage 1, a user can transform from normal human to his/her 'Victor' form. After 6 weeks, a user evolves into stage 2, when he/she is permanently transformed into a 'Victor' form, while in stage 3, the tanned skin turns into a dark red, and the power of energy drain greatly increases. Black Kakugane have all the functions of a standard Kakugane. The user can also gather up corpses of creatures the user drained energy from and make a larger copy of himself. Buso Renkin created by Black Kakugane tend to be much stronger, since they make their users' bodies so much stronger.

White Kakugane
Developed by Alexandria, a White Kakugane is the exact opposite of a Black Kakugane. It holds the ability to nullify a Black Kakugane's power, restoring a person with a Black Kakugane to normal.

Kazuki's Kakugane that Tokiko took back from Alexandria was a 'test model' that was disguised as a normal kakugane. However, it proved to be unstable when it was in close proximity with a Black Kakugane; in this case, Victor's Black Kakugane I. Alexandria then developed another kakugane based on Black Kakugane II, moving past the test stage. This Kakugane was used in an unsuccessful attempt to restore Victor to normal; a Black Kakugane user in stage 3 can only be restored to stage 2 via one White Kakugane, and so on.

Papillon was able to make a White Kakugane based on his own knowledge and the research Dr. Butterfly and Alexandria left behind. Using them, he was able to develop a White Kakugane from scratch, and used it to change Kazuki back to normal in Buso Renkin Period. His devices were then used to create another White Kakugane to restore Victor back to normal. Other than the converted Kakugane II, all White Kakugane produced are not numbered. It is possible to have more than one White Kakugane in a person's body, as shown by Victor, who has two White Kakugane in his body by the end of the story.

Homunculus
A homunculus is created when an embryo-like creation from a plant, animal, or even a human is placed inside a human. The embryo then crushes the brain and takes control of the body, giving it abilities that mimic the natural talents of the embryo's origin.

Animal-type and Plant-type homunculi possess strength relative to their animal or plant base as well as retaining their sentience (they have the intelligence and reasoning of a human, but consider themselves to be an animal or plant). To activate their abilities, they have to 'transform', usually resulting in a large version of its base (an Eagle-type homunculus would become a giant eagle, for example). Often the homunculi's creator would have to brainwash them into following their creator with blind loyalty, though a few have been known to do so by their own choice.

Human-type homunculi do not change form, but merely gain the strength and regenerative powers of a homunculus while retaining their human form and mind, or at least a humanoid shape (as the embryo for a human homunculus almost always comes from the human him/herself). Human-type homunculi have one distinct advantage over Animal or Plant-types; they have the ability to use Buso Renkin (only humans can use Buso Renkins).

Most homunculi have the urge to eat other humans, but in episode 25 Papillon tells Victoria that eating humans doesn't whet his appetite. Victoria explains that homunculi eat humans because they desire to regain the aspects of humanity that they gave up. She then tells Papillon that because he no longer has any connection to humanity (or rather, that he no longer desires to be human), he has become something other than human or homunculus, but rather a "superhuman".

Characters

Kazuki Muto
Voiced by: Jun Fukuyama
A 16-year-old boy who attends a private academy with his sister. After becoming involved in Tokiko Tsumura's fight and subsequently being killed and revived by a Kakugane (which later turns out to be a black Kakugane), he is told to simply return to his ordinary life, but instead insists upon assisting Tokiko in her battles. Kazuki is very enthusiastic and friendly, and cares deeply for his friends and sister, Mahiro, tending to put himself in danger or difficulty in order to assist or protect others. Although he has an unusual way of showing it, he does have feelings for Tokiko Tsumura.

The Kakugane Tokiko used to revive Kazuki turned out to be Black Kakugane III, which transformed him into a being just like Victor. He is then pursued by the 'Muto-assassination team', as well as his former commander, Captain Bravo. During his assassination, he was dubbed 'Victor III' by the Alchemy Warriors. In the end, he sacrifices himself when he sends himself and Victor to the moon with Sunlight Heart +. In Buso Renkin Period, however, he returns to Earth successfully with help from Victor's Buso Renkin, Fatal Attraction. As soon as he returned to Earth, he and Papillon settled their scores, with Kazuki claiming victory. After this, he returns to a normal life with Tokiko.

Buso Renkin: Sunlight Heart (+)
Seeing as the Kakugane doubles as his heart, his Buso Renkin plays a unique and critical role in Kazuki's survival. Once invoked, his Buso Renkin, Sunlight Heart, takes the form of a spear-lance with a large decorative cloth attached, which alchemic power enables the cloth to turn into an energy force when it resonates with Kazuki's willpower. The cloth's energy can be used as propulsive kinetic energy for forward charging, or, for instance, dissipating the gravitational forces of a fall. This ability is the origin of its name as the light it radiates shines like the rays of the sun, hence "Sunlight Heart." First believed to be Kakugane LXX (70), Kazuki came to discover he was actually in possession of the Black Kakugane III (3); with the actual Kakugane LXX (70) being in the possession of Dr. Butterfly. Since then, the Sunlight Heart has since changed into the Sunlight Heart +. The overall lance takes on a smaller, sleeker design. This new streamlined version, at first glance, seems inadequate as a lance due to its decreased reach and size. However, the Plus's true properties reveal themselves as being able to vastly increase its reach and power; responding to Kazuki's willpower to unleash its self-contained energy, disassembling into, and arranging its core components in the most efficient formations. To this extent, it activates its alchemic powers in the same manner as the original Sunlight Heart. Though lacking the cloth, it can generate propulsive forces from the point at the end of the handle (which is shaped like the original Sunlight Heart, though much smaller) which opens to release kinetic energy. It can also fire off blasts of internal energy. Sunlight Heart + is last seen in Buso Renkin Period, when it was destroyed by Papillon's Buso Renkin, Neardeath Happiness, with only the original spear's head remaining (however since it is seen that Buso Renkin regenerate as time passes, Sunlight Heart would've been repaired).
Kazuki has also adopted the habit of naming certain attacks; most frequently are:
Sunlight Slasher: formerly named the "Jousting Slasher," is a straight charge attack under the propulsion of cloth's energy at full capacity.
Sunlight Flasher: formerly the "Jousting Flasher," uses a burst of bright light from the cloth to blind the enemy.
Sunlight Crusher: formerly the "Jousting Crasher," is his strongest attack, which wraps the cloth around the lance and uses its energy force to increase the overall speed and destructive force of the charge.

Tokiko Tsumura
Voiced by: Ryōka Yuzuki (Japanese), Tara Platt (English)
A 17 year-old alchemy warrior that was assigned to take care of a homunculus problem in Kazuki's town. When Kazuki tried to save her from a homunculus (in actuality, she had the situation under control) she felt a sense of attachment to him and revived him with a Kakugane, intending to make sure that he never gets killed again. Tokiko is very dedicated to her job, claiming that she hates all homunculi, and quit going to school in order to be more efficient. This hatred comes from the trauma she suffered as a little girl, when all the people in her school were killed or eaten by homunculi to save her. As such, she is serious almost all the time, which leads to some awkward situations when with Kazuki and his friends. She is later assigned to be a student at Kazuki's school by Captain Bravo. She eventually falls in love with Kazuki and stays with him at the end of the series. Her quote when battling is "I'll rip your guts out." True to her words, the Valkyrie Skirt has torn many enemies apart.

Buso Renkin - Valkyrie Skirt
Tokiko's Buso Renkin, the Valkyrie Skirt, takes the form of four scythe-like blades that attach to her legs. She is capable of using them a number of ways, from attacking numerous enemies at once to using them to boost her jumps and cushion her landings. The name comes from how in stand-by mode the blades fold up, and in her school outfit, her skirt resembles that of a Valkyrie. Unfortunately, the weapon is ill equipped to fight enemies of great physical power or endurance. Tokiko holds Kakugane XLIV (44).

Koshaku Chono
Voiced by: Mitsuaki Madono (Japanese), Spike Spencer (English)
Better known as Papillon in the series. He is a genius student from Kazuki's school and was meant to be heir to the Chono family fortune. However, he is also deathly ill and has had to repeat a year of school due to the amount of time he has needed to spend in the hospital. Upon discovering a 100-year-old research diary from his great-great-grandfather he learned of alchemy and the process of making homunculi, experimenting with various animals first before turning himself into a human-type homunculus, renaming himself "Papillon". However, he's imperfect, as he used his own, sick cells to recreate himself, he now suffers from the same sickness, but won't die. He began his move by eating every member of his family who couldn't recognize him as Koshaku, but as his brother Jirou, to the point of even killing his own father and brother. To prevent Papillon from eating more people, Kazuki had no choice but to kill him.

As Papillon, he is flamboyant and reckless. He appears in public wearing his mask and in revealing or outlandish outfits, apparently oblivious to or possibly enjoying the stares of bystanders. He also slowly loses a thirst to eat human and his wish to burn the world to the ground, slowly becoming something more than a homunculus as Victoria states (She theorizes that a homunculi's desire to eat humans comes from their desire to be one, as Papillion has no desire to return to humanity, he loses his appetite for them.). After his initial defeat at the hands of Kazuki, he teams up with the homunculus Dr. Butterfly, his still-living great-great-grandfather. After the LXE fell, he became a team with Ōka to turn Kazuki back to normal again, in order to duel and kill Kazuki. In the end, he does restore Kazuki to a normal human with the white Kakugane he created himself, and loses the duel. However, Kazuki does not kill him because he already killed him once and thought that he was a good person. He then becomes one of the many urban legends in Japan, nicknamed 'Butterfly Man Papillon', where he is now loved by all of the people in the city, becomes friendly with everyone, and even has a promotion deal with the local fast food restaurant.

Buso Renkin - Near-death Happiness
Papillon's Buso Renkin, when activated, is black gunpowder that typically takes the form of a pair of butterfly wings on his back. He also can create a number of small butterflies from it that explode on impact and that he can use offensively or create a large butterfly which he can ride on. When all of the butterflies are used up, it takes three days to regenerate. Papillon holds Kakugane LXI (61).

Alchemy warriors

Captain Bravo
Voiced by: Masashi Ebara
Mamoru Sakimori, better known as Captain Bravo in the series is Tokiko's commander, who dresses in an outfit that covers every inch of his body except for his eyes. Though Tokiko assumed this was to protect his identity, Bravo actually has no qualms with showing his real appearance when he acts as Kazuki's dorm supervisor. He claims that he doesn't use his real name because it's cooler that way, (that's what Kazuki thought the reason was, or more like he thinks it's cool) but the truth is he abandoned the name after his first and last mission in the "Showusei Team", who only managed to save Tokiko. He acts as a father figure for Kazuki. He's also the only character besides Kazuki who loves green vegetable juice. During the Muto assassination arc, he tried to kill Kazuki up to a point where he threw him off a cliff, but he later defends Kazuki when Kazuki defeats him. He was critically injured by Hiwatari when he gave up his silver skin to cover up Kazuki and Tokiko from getting killed by Hiwatari's Blaze of Glory. Bravo remained conscious and controlled Silver Skin to prevent both Hiwatari and Kazuki from harming each other till Showusei appeared and stopped both raging warriors. True to his name, the captain has a tendency to say "Bravo" when applauding someone. He claims that he has 13 different attacks regardless of identity, such as 'Meteor-Bravo Kick' (流星・ブラボー脚), and 'Charming-Bravo Kiss' (悩殺・ブラボキッス).

Buso Renkin - Silver Skin
Double - Silver Skin: Another Type
His outfit is actually his Buso Renkin, called Silver Skin. Upon impact from an attack, his outfit hardens into a regenerating metal; it is known as the Buso Renkin with the strongest defense power in all known Buso Renkins (in contrast with Hiwatari's Blaze of Glory, which has the strongest offense powers). In addition to all this, Bravo has immense physical strength. Later it is revealed that the Silver Skin has another ability, which is named Silver Skin Reverse (银皮反穿). This ability is used on the opponent to restrict his/her moves, rendering the victim defenseless against Bravo's powerful physical attacks. However, Reversed Wearing can be easily stopped if someone runs into it, as Bravo cannot control whom it can capture. Bravo owns Kakugane C (100), he also uses Kakugane LII (52), something left by his dead subordinate, in several occasions, such as the battles against Moon Face, and against Kazuki. His second Silver Skin resembles a pirate, while having an opposite palette as the original silver skin. In reversed wearing the Silver Skin will reverse its colors. The Silver Skin, in both forms, is also the only Buso Renkin invulnerable to Victor and Kazuki's energy drain. Silver Skin seems to also be able to be operated as a space suit, as shown by Tokiko in Buso Renkin Period, she was able to use it to get to Kazuki in space (with Silver Skin fragments around her serving as an oxygen barrier).

Gōta Nakamura
Voiced by: Shinji Kawada (Japanese), Liam O'Brien (English)
Among the Alchemic Warriors, he is the junior to Tokiko, whom he has a big crush on. He longs for the same relationship she shares with Kazuki, and as a result, finds himself disliking him. Yet despite all this, he cooperates with Kazuki and Tokiko as they try to uncover the conspiracy behind the Black Kakugane. Gōta is a strategic planner and fights with variations of his Buso Renkin. As shown in his fight against Negoro, he was able to figure out Secret Trail's secret and use it against Negoro. In Buso Renkin After, he joins Ginsei High with Busujima.

Buso Renkin: Motor Gear
Motor Gear is the form of his Arms Alchemy using Kakugane LV(55). It takes the form of a pair of gear-shaped chakrams, which has a variety of applications ranging from close-to-long range weaponry to increased mobility for Gouta himself. Motor Gear is regarded as one of the weakest Arms Alchemy currently in use; however, it more than makes up for this with its speed and size which makes it extremely hard to see, along with the wide variety of uses the Motor Gear can utilize in combat.

Shōsei Sakaguchi
Voiced by: Sho Hayami
The leader of all Alchemy Warriors in Asia, before he became the leader, he was the captain of 'Shōsei Team', which included Bravo, Hiwatari and Chitose. Shōsei is the only person able to stop anything Hiwatari does. He has the peculiar quirk of beating up anyone who disagrees with him, and doing so while laughing.

Buso Renkin - Buster Baron
The Buster Baron is a gigantic knight-like robot that's 57 m high, with a weight of 550t that attacks primarily with its fists (visually based on Armor Baron, a character from Watsuki's earlier manga Gun Blaze West). Its left and right shoulders, however, can be inserted with up to six alchemy warriors and their Kakuganes, and the Kakuganes of warriors inside become amplified (for example, making a normal sword an extremely large sword). It can also be summoned with just one of its body parts. However, it proves to be no match against Victor even with six other Buso Renkins, the Baron was beaten by Victor in his normal size (Victor fought the Baron with a fake body formed of dead sea animals). Shōsei holds the number XVII (17).

Sekima Hiwatari
Voiced by: Tomokazu Seki (Japanese), Kyle Hebert (English)
Captain Bravo's former teammate and one of the Alchemy Commanders. He is the leader in charge of Muto-assassination team. He has a bad temper and threatens to kill people, almost never plans things out first, and is willing to use the same tactic the enemy uses to beat the enemy. During the Muto-Assassination arc he said, "Unreasonable things must be beaten with the same unreasonable tactics." After Maruyama, Negoro, and Bravo were beaten, Hiwatari appears in front of Kazuki and co. to kill them. While Bravo tried to stop him, he released a flame storm that engulfed the entire construction yard thus leaving only the two silver skins intact. He went in shock after seeing Bravo sacrificing himself to cover his Silver Skin around Kazuki and Tokiko, and is angered by how Kazuki wants revenge. The two of them engaged in a fierce battle, only to have each of their attacks shielded from the other person by Silver Skin fragments. They were then stopped by Sakaguchi Showusei, the Asia leader of the Alchemy Warriors. Hiwatari's special ability is to talk while smoking. Hiwatari is also known as the Alchemy Warrior with the strongest offense with his Buso Renkin, the Blaze of Glory.

Buso Renkin - Blaze of Glory
Blaze of Glory is a Buso Renkin like a napalm bomb with hexagons all over the bomb itself. The Buso Renkin gives Hiwatari the ability to become one with flames, as such, the napalm bomb usually does not appear. The further the flames burn, the more powerful he is. As such, physical attacks will not work on him, as shown in his battle with Gōta. He was unaffected even when Motor Gear slit through his throat; instead of dying, he released flames from his wound to attack Gōta. Blaze of Glory is able to release a flame storm with a temperature as high as 5100˚c and a radius of 250 m. Hiwatari holds Kakugane XX (20).

Chitose Tateyama
Voiced by: Yu Kobayashi
No.1 of the Muto-Assassination team. Like Bravo and Hiwatari, Chitose was part of the Showusei team. She's a serious woman that specializes in scouting, chores, and seems to like to cosplay (denied by herself). She used to have a long braid behind her head and liked to cry, but turned into a more mature person after the first and last mission of the 'Showusei Team'. She is an expert in shredding apple skin. In the anime, she leads the Victor search team composed of Inukai, Busujima, Maruyama and Shusui to kill Victor, but they were defeated and forced to retreat, and only escaped when Chitose used her Buso Renkin, Hermes Drive, to teleport everyone out. She tended to Captain Bravo, who was in the hospital while recovering from his previous battle with Muto Kazuki.

Buso Renkin - Hermes Drive
The Hermes Drive is a Hexagon Radar-type Buso Renkin that can detect enemies and allies known to Chitose. It can also be used as a teleport device, the maximum weight of teleporting is 100KG. The Hermes Drive itself can also be used as a hitting weapon and even as a mini-shield. Chitose holds the kakugane number XCV (95)

Hanaka Busujima
Voiced by: Sayuri Yahagi
Always seen masked till Buso Renkin After, the epilogue chapter. She cares deeply about Hiwatari and worries about him. In Buso Renkin After, she is revealed as an extremely shy girl. She keeps her Buso Renkin, Aerial Operator, on her at all times because of her shyness. Her special ability is that she can guess the oxygen density accurately. In the anime, she is part of the Victor Search team with Inukai, Maruyama, Chitose and Shusui, they were sent to find and kill Victor, but they were easily defeated. They only escaped when Busujima released a large cloud of smoke, giving time for Chitose to teleport the others out.

Buso Renkin - Aerial Operator
Aerial Operator is a Buso Renkin in the form of a gas mask capable of mixing all gas type elements into poisonous or explosive mixtures. The Buso Renkin itself is also capable of flying, viewing far objects (like binoculars), night vision, magnification, and filtering. Busujima uses Kakugane XXXIX (39).

Genji Ikusabe
Voiced by: Tsuyoshi Koyama
He has an extreme thirst to fight Homunculi, and is the record-keeper of 'Most Homunculi killed' (332), even more than the number of homunculi killed by Hiwatari and Bravo combined. Ikusabe's powers come from his Buso Renkin, the Jumonji spear Gekisen's recovery ability, his special ability and habit to eat remains of Homunculi he's killed to increase his power and stamina, and the times he can use the recovery ability. Unlike Negoro, Ikusabe cares more about the process of battling then claiming victory, and quit the mission to kill Kazuki when he was defeated by Papillon. In the anime, it is not shown that he eats homunculi, nor does he send Papillon to Kazuki and Gōta. Instead, he falls to the ground after Papillon defeats him.

Buso Renkin - Gekisen (激戦,lit. Intense War)
A Jumonji spear (Cross-like spear) that has the special ability to recover any wound to its holder, in this case Ikusabe himself. The spear is even capable of reviving Ikusabe even if Ikusabe's body is blown to pieces. However, Gekisen's flaw is that since it recovers automatically and at a high speed, if something gets caught into where one of Ikusabe's body parts should be, the recovery will fail. If Ikusabe is separated from his spear, then the weapon cannot heal him. Ikusabe uses Kakugane XII (12).

Madoka Maruyama
Voiced by: Junko Minagawa
No.4 of the Muto-assassination team. Maruyama is a bishounen that is usually under the disguise of a fat, chubby ball, until Tokiko cut open the disguise with her Valkyrie Skirt. He was able to shrink Tokiko to 34CM in their first battle, then seemingly shrink her to nothing in their second battle, only to find Tokiko still has 4CM remaining and went into his stomach. He was defeated as his guts were ripped out by Valkyrie Skirt. His special ability is that he can draw a circle without using a compass. In the anime, he, Inukai, Chitose, Busujima and Shusui were sent to fight Victor, but lost against Victor's Buso Renkin, Fatal Attraction, and was forced to retreat. He doesn't use his fat man disguise in the anime either.

Buso Renkin - Bubble Cage
Bubble Cage is a large number of wind-navigated fire balloons that will shrink the person it hits by 15CM per hit; a person will vanish if he/she gets hit by too many bubble cages. By detonating one Bubble Cage, he can create wind force that'll drive other Bubble Cages towards the enemy. Although these balloons make laughing sounds when moving, they have no intelligence. Maruyama owns the Kakugane XXXII (32). In the anime, Bubble Cage does not shrink the target, but when it explodes, it splits into more Bubble Cages.

Shinobu Negoro
Voiced by: Kenji Hamada
No.5 of the Muto-assassination team, he is an extremly cold character. Almost always hidden inside his own 'space' created by his Buso Renkin, the Secret Trail. His clothes and his hair are sewn into it as well. The opposite of Ikusabe, he cares about claiming victory more than the process of beating his enemies. He was later defeated by Gōta when he hid in his own space after being ambushed by Gōta's Motor Gear, only to have the two chakrams hit him again as both chakrams had Negoro's own blood. He is able to become completely unnoticed in a crowd of people.

Buso Renkin - Secret Trail
A katana-shaped Buso Renkin that can cut open paths to another space that only Negoro, who has the DNA that Secret Trail will recognize, can enter. The katana itself can also be thrown in and out of the real world and the special space freely. Negoro owns the Kakugane XIV (14).

Rintarou Inukai
Voiced by: Makoto Yasumura
No.6 of the Muto-assassination team. Known to have a strong sense of pride, and rather die then getting defeated and left alive. Inukai uses the Buso Renkin "Killer Rabies," two mechanical dogs that are commanded by a dog flute. He claims that anyone not holding the flute will get killed when his dogs are in berserk mode. However, at one point, Gōta used this to his advantage and took Inukai's flute, resulting in Inukai nearly getting killed by his own dogs. He can also imitate a dog's bark. In the anime, he, Maruyama, Busujima, Chitose and Shusui were dispatched to take out Victor, but they were forced to retreat.

Buso Renkin - Killer Rabies
Killer Rabies is a pair of mechanical dogs that are commanded by a dog flute held by Inukai; these dogs have twice the smelling power and ten times the strength and stamina of normal dogs. When in berserk mode, the dogs will kill anyone not holding the flute. Cutting both dogs in half during this mode will not affect them, since with lighter weight they move even faster. The only way to defeat the Buso Renkin is to cut the heads off. Inukai uses Kakugane XCII (92). In the anime, the dogs were sent to fight Victor, but they proved to have little effect on the giant warrior; one dog was crushed in the neck with Victor's bare hands, and the other was crushed by the gravity force Victor generated with his Buso Renkin, Fatal Attraction. According to the manga data page, Killer Rabies were supposed to be purple-red and purple-blue; however, in the anime, they are portrayed as white dogs with purple tails.

Hayasaka Twins
The Hayasaka twins attend the same academy as Kazuki Muto. When they were children, the two constantly played the "marriage" game with their mother. They were always told never to leave the room they were in and to never go outside. One day their mother died overnight. The Hayasaka twins were unaware that she was dead and only came to a realization of this when her body began to rot. Upon seeing this they tried to leave the house for help but found that the door was chained and bolted shut. Trapped in the apartment, the twins nearly starved to death but were rescued by police who had come to arrest their mother for kidnapping the twins. While in the hospital, they overheard their real parents claiming that the children were no longer theirs. Not wanting to be separated, the twins ran away from the hospital to live together. Eventually they were recruited into the LXE where they decided to work for the homunculi there so that one day they too could become homunculi and live together forever. Their lives changed when they met and later fought against Kazuki Muto and Tokiko Tsumura.


Shusui Hayasaka
Voiced by: Kishô Taniyama
Shusui is Ouka's twin brother. He is the younger of the twins. He and his sister are not actually homunuculi. He becomes an Alchemy Warrior as well after LXE falls. He's smart, the best at Kendo at Ginsei High, along with being the vice president of the Student Council, and as Kazuki and the others state, No. 1 even in terms of genital size. In the anime, he was recruited by Chitose to be a part of the team dispatched to take out Victor; however, they were defeated and forced to retreat.

Buso Renkin - Sword Samurai X
Shusui's Buso Renkin is a sword that has a small charm on the end attached with a rope. The sword absorbs energy into the charm, and at the users command can make the sword discharge energy coming from the charm. 'Samurai X' is a sort of easter egg that refers to the English name of Rurouni Kenshin, when translated by ADV. Shusui owns Kakugane XXIII (23).

Ouka Hayasaka
Voiced by: Hitomi Nabatame
Ouka is the twin sister of Shusui. She is the student president of Ginsei High. She and Shusui originally worked for the LXE, after the LXE fell to pieces. Ouka worked for Papillon in order to save Kazuki from getting killed. She specializes in hacking and computer engineering as well as having a sharp mind. In her profile, it says one of her "favorites" is Espresso.

Buso Renkin - Angel Gozen
Angel Gozen is a set consisting of a bow, an autonomous robot, and a glove. Attacks consist of having the robot aim a stream of arrows at a target (the robot is an accuracy mechanism), and by pulling back on the bowstring with the glove, an arrow that transfers damage from the target to the user. The robot was unable to speak until Bravo turned on the sound mechanism. Ouka has Kakugane XXII (22), and later Dr. Butterfly's LXX (70) While using LXX, Gozen's wings turn into butterfly wings.

Gozen is the automatic doll Buso Renkin that is Ōuka's "other" personality. Gozen is also the main messenger between Papillon and Ōka, since Gozen's heart-shaped ornament on its head can receive and send messages and be used as a camera. Gozen is very hyperactive and loud (unlike Ouka) and has a tendency to have its own parts (wings, head ornament) fall off whenever Papillon does something strange. He also has a serious case of urinary incontinence when he is frightened, as demonstrated when Tokiko threatened to tear him apart for his sarcasm.


L.X.E. (League of eXtraordinary Elects)

Doktor Butterfly
Voiced by: Katsumi Chou
He is Chōno Kōshaku/Papillon's still-living great-great grandfather, and is also the leader of LXE (League of eXtraordinary Elects). His original name was Chōno Bakushaku (蝶野爆爵). He has a butterfly-shaped mustache. His battle outfit resembles Papillon's outfit, except that it's white, and Dr. Butterfly attached a cape to it. He was killed by Papillon just before Victor awakened.

Buso Renkin - Alice In Wonderland
Doktor Butterfly's Chaff Buso Renkin has the same wing-like structure as Papillon's Neardeath Happiness, but it confuses the nervous system. In concentrated mode, it's also able to directly affect a person's brain, giving the person hallucinations and illusions. Alice In Wonderland is also capable of disrupting radio and electric waves, and when in contact with water dews, create a mist. Doktor Butterfly holds Kakugane LXX (70), the real version of the Kakugane that Kazuki owns.

Moon Face
Voiced by: Tomokazu Seki
Originally known as Lunar Nicholai, he is a homunculus with a moon-shaped head and a higher-up of the LXE. He has a tendency to say "Moon~" whenever possible. After the LXE was defeated, Moon Face was put into custody by the Alchemy Warriors, and later placed on the moon with the other homunculus, led by Victor. He joined the LXE 100 years ago when he came from Russia to Japan with reasons unknown.

Buso Renkin - Satellite 30
Moon Face's Buso Renkin allows him to create up to 30 copies of himself, each copy having a different head representing the different phases of the moon (the New Moon copy has no head). Since this uses a large amount of energy, only a homunculus like Moon Face can use it. Also, the more copies Moon Face makes, the harder it is for him to coordinate complicated moves. Unless all 30 are defeated at once, more copies will always be made, as every Moon Face made is the real version. Moon Face holds Kakugane XXX (30). Watsuki once stated that he got the idea of Satellite 30 from The Matrix Reloaded character Agent Smith.[citation needed]

Kinjo
Voiced by: Hiroshi Tsuchida
A lower ranked member of the LXE, Kinjou was assigned to spy on Papillon, and finish off the Alchemy Warriors of Ginsei High when possible. He has a tendency to say 'Hyahou' and is loud and arrogant. He also has the ability to talk without his tongue. Kinjou was defeated by Bravo. but finished off by his teammate, Jinnai. As a side note, he was based on Inui Banjin from Watsuki's previous series Rurouni Kenshin.

Buso Renkin - Peaky Gulliver
Kinjou's Buso Renkin, Peaky Gulliver is a gauntlet attached to his right arm, which is able to change its size at will, even able to make it larger then Kinjo himself, and has small rockets to propel attacks or allow flight. However, this proves no use against Captain Bravo's Silver Skin. Kinjou uses the Kakugane LII (52), which originally belonged to a spy sent by Bravo to spy on the LXE, but was found and killed by Moon Face. The name of the Buso Renkin is based on Gulliver's Travels, as are his special moves, 'Laputa Falls' and 'Brobdingnag Knuckles/Finger'.

Jinnai
Voiced by: Susumu Chiba
Jinnai is another lower ranked homunculus in the LXE. like Kinjo, he was sent to spy on Papillon. As soon as Kinjo failed to kill the Alchemy Warriors, Jinnai finished Kinjo off with his Buso Renkin, the Noisy Hamelin. Later that night. He uses the Noisy Hamelin to control Ginsei High students to take back Kakugane LII (52) from Tokiko. He began to retreat when he first took damage from Tokiko's Valkyrie Skirt and attempted to eat Chisato while she was listening to music in her dorm room. He attempts to consume her, but Tokiko managed to force him out into the forest where she cuts of his arms and legs with the Valkyrie Skirt. Tokiko returned his appendages after he promised he'd tell her anything she wanted to know about the L.X.E, but his arms and legs were attached to the wrong places. When he realized this, he attacked Tokiko. She ripped him apart once more and this time she killed him. He was based on Otowa Hyoko from Watsuki's previous series Rurouni Kenshin.

Buso Renkin - Noisy Hamelin
Based on The Pied Piper of Hamelin, Noisy Hamelin is a Steel Whip type Buso Renkin, capable of vibrating itself and emitting powerful sound waves that can hypnotise anyone within its range. Jinnai uses Kakugane LXI (61), after his death, this kakugane was claimed by Papillon.

During LXE's attack on Ginsei High, Suzuki used his status to isolate Kazuki, however, he was outsmarted by Rokumasu and his plans were thwarted. He is not a homunculus, nor does he possess a Kakugane, as stated by Dr. Butterfly.


Victor and his Family

Victor
Voiced by: Rikiya Koyama
Victor was once the leader of the Alchemy Warriors 100 years ago. Originally, Victor used a regular kakugane until he sacrificed himself to kill the leader of the homunculi of that era. In order to save him, his wife Alexandria transferred Black Kakugane 'I' into his heart. However, the power went berserk and Victor killed everyone in the lab, as well as critically injuring Alexandria. Victor was then forced to flee his home, pursued by Alchemy Warriors and the Homunculus group lead by his own daughter, Victoria, who was also turned into a Homunculus against her own will. Victor managed to destroy a large portion of both forces before he fled to Japan, where he met Chōno Bakushaku, before he became Dr. Butterfly. The two men then struck a bargain; if Victor gave Dr. Butterfly his knowledge of Alchemy, Dr. Butterfly would heal Victor in return.

After 100 years, the plan succeeded; Victor was healed and re-appeared in LXE's Ginsei High School attack. He managed to kill Kazuki once more, by crushing the Sunlight Heart with his Buso Renkin, Fatal Attraction. This damaged Kazuki's Kakugane, and by doing so, Victor caused Black Kakugane 'III' to awaken. He and Kazuki soon went into a battle, but both warriors soon ran out of energy and Victor was forced to retreat. Afterwards, he traveled around the world, absorbing large amounts of energy from locations such as New York, Paris, and even the Arctic. Eventually he was forced into the Pacific Ocean, where he evolved from stage 2 to stage 3, and battled Sakaguchi Showusei's Buso Renkin, the Buster Baron. However, he used the corpses of ocean creatures, whose energy he had absorbed, and single-handedly destroyed Buster Baron with his own Buso Renkin, the war-axe, Fatal Attraction. He confronted Kazuki then, with Kazuki forcing White Kakugane 'II' into his body. However, White Kakugane 'II' was only able to revert him back from stage 3 to stage 2. As a last resort, Kazuki used the Sunlight Heart + and sent both of them to the Moon.

In Buso Renkin Period, Victor's heart was shaken by Kazuki's determination to protect Earth, and he used Fatal Attraction to send Kazuki back; however, Kazuki dragged Victor along, sending both of them back to Earth. Victor reverted back to his human form, and requested to be turned into a Homunculus. He then led all the homunculi and headed towards the Moon, seeking to make it the new home of homunculi.

During the 100 year interval, to cover the Black Kakugane incident up, the Alchemy Warriors used fake information in their database. Instead of going berserk, the fake information reads that Victor betrayed the warriors and turned himself into a homunculus, then headed for Japan to join the LXE. He does not hold any special ability or special points, since he's better than most people in doing anything.

Buso Renkin - Fatal Attraction
Victor holds Black Kakugane I (1), the Buso Renkin, Fatal Attraction is a gigantic war-axe that is capable of manipulating gravity. It can manipulate the gravity direction on larger or smaller scales. It can used to increase the gravitional pull on an object or reverse it. The axe can also be separated into two to be used as double tomahawks.

Alexandria
Voiced by: Masako Katsuki
Victor's wife, her body was paralyzed after Victor went berserk, and she moved her own brain into a container in the Newton's Apple All Girls Academy. She lives inside her daughter Victoria's Buso Renkin, UNDER GROUND SEARCHLIGHT. Inside there she kept cloning her own brain to increase her mental abilities, and to complete Kakugane II (2). However, after 100 years her cells begin to die, and she fades away before the confrontation between Victor and Kazuki. Even after 100 years of what Victor did to her and their family, she still loves him. While still in her human form, she specializes in making meat pies.

Buso Renkin - Rurio Head
Rurio Head is Alexandria's only means of communication to the outside world, usually worn by Victoria. It is capable of controlling its wearer and capable of finding memories of its wearer. Rurio Head usually attacks with its cape knives. It has been able to control Victoria, Chitose, and Gōta. Alexandria uses kakugane L (50).

Victoria
Voiced by: Rie Kugimiya
Victor and Alexandria's daughter. After her father went berserk, and her mom is paralyzed, she was forced to become a homunculus and lead a squadron of Homunculi to kill Victor. Afterwards she hated Alchemy just like her father. She usually disguises herself as a student of the Newton's Apple All-girl academy. She likes to eat "Mama's special", which is a mosiaced piece of food; which is in fact a piece of a human corpse. In Buso Renkin Period, we see that she follows her father to the Moon. She's known to have a sharp tongue.

Buso Renkin - UNDER GROUND SEARCHLIGHT
UNDER GROUND SEARCHLIGHT is a trench type Buso Renkin, which allows Victoria to generate a hidden cave that can only be entered when Victoria opens it.
